Performance of glomerular filtration rate estimating equations in HIV-positive and HIV-negative participants.

<p>CI, confidence interval; eGFR_cr, eGFR_cys, and eGFR_cr-cys are glomerular filtration rates estimated by CKD-EPI equations using plasma creatinine, cystatin C, and both biomarkers, respectively; P₂₅ and P₇₅, 25^th and 75^th percentiles, respectively.</p>a<p>Comparisons of a single equation between the HIV-positive and HIV-negative groups. P values in bold font indicate difference is statistically significant accounting for multiple comparisons (see text).</p>b<p>Accuracy defined as percentage of estimated GFR values within 30% of measured GFR.</p>c<p>Comparisons of a different equations within the HIV-positive or HIV-negative group. P values in bold font indicate difference is statistically significant accounting for multiple comparisons (see text).</p>d<p>Bias defined as difference between estimated GFR and measured GFR (mL/min/1.73 m²).</p>e<p>Precision defined as interquartile range of bias.
